* TLS v1.1 and v1.2: The protocols which should be used wherever possible.
All CBC based ciphers are supported since Java 7, the new GCM modes are supported since Java 8.
* TLS v1.0: Still supported but is affected by the link:https://cve.mitre.org/cgi-bin/cvename.cgi?name=cve-2014-3566[POODLE attack.]
To support older browsers this protocol version is still needed.
* SSL v3: is now deprecated and should *only* be enabled if you still need to support very old browsers like Internet Explorer 6 on Windows XP which does not support TLS 1.0 (or is disabled by default).
===== Older Protocols
Both TLS v1.0 and SSL v3 are no longer supported by default. If your Jetty implementation requires these protocols for legacy support, they can be enabled manually.
____
[NOTE]
Once TLS v1.3 is released, there will be no workaround available for TLS v1.0.
Plans for TLS v1.3 include banning ciphers with known vulnerabilities from being present at any level.
It is recommended to upgrade any clients using these ciphers as soon as possible or face being locked into a outdated version of Jetty, Java or even OS.
____
By default, Jetty exclused these ciphers in the link:{GITBROWSEURL}/jetty-util/src/main/java/org/eclipse/jetty/util/ssl/SslContextFactory.java#L253-L256[`SslContextFactory`.]
You can re-enable these by re-declaring the ciphers you want excluded in code:
[source, java, subs="{sub-order}"]
----
SslContextFactory sslContextFactory = new SslContextFactory();
sslContextFactory.setExcludeCipherSuites(
"SSL_DHE_DSS_WITH_DES_CBC_SHA",
"SSL_DHE_DSS_EXPORT_WITH_DES40_CBC_SHA");
----
If, after making these changes, you still have issues using these ciphers they are likely being blocked at the JVM level.
Locate the `$JAVA_HOME/jre/lib/security/` directory for the `java.security` file and examine it for any configuration that is excluding _ciphers_ or _algorithms_ (depending on the version of the JVM you are using the nomenclature may be different).
